My Mom's Compaq Presario V6000 is showing no picture on the screen and continuously power cycles about every 30 seconds unless you hold the power button down to turn it off. All of the lights are working and you can hear the disk drive working when it first comes on.

I have taken it in to a local shop and the tech thought it might be the mother board. I was just hoping to see if anyone else had any other thoughts.

Thanks

Short summary and practical next steps for ’s Presario V6000 thread: the symptom set — no display plus repeated power cycles — most commonly points to a motherboard-level failure (often the GPU/BGA area on V6000-era HP/Compaq boards). That matches ’s and the shop tech’s read of the problem, though simple power or firmware issues can sometimes mimic it. (laptoprepair101.com)

Suggested diagnostic sequence (low-cost, low-risk first):

  1. Verify the AC adapter and battery indicator (use a known-good adapter if available).
  2. Power drain: unplug, remove battery, hold power button ~15–20 seconds, then power on from AC only.
  3. Minimal boot: remove all non‑essentials (optical, USB devices, modem/wireless cards), reseat RAM and try a single module in the primary slot; watch for beeps or LED blink codes.
  4. Try an external monitor to separate display-panel problems from GPU/system failures.
  5. If any BIOS access is possible, Load Setup Defaults (HP’s BIOS reset paths) before hardware changes; CMOS battery/jumper clears are the next safe step for advanced users. (support.hp.com)

If data is the priority (good call raised by and ): the hard drive can be removed using the V6000 service/maintenance guide and attached to another PC with a SATA‑to‑USB adapter or enclosure to copy files. Check for drive encryption (BitLocker) first — recovery keys (Microsoft account, Azure AD or printed/USB copies) are required if enabled. Refer to the V6000 manual for safe disassembly. (manualslib.com)

Context and caution about repairs: DIY “reflow” or oven-bake fixes for these HP models are widely discussed because the era suffered GPU/package failures; they sometimes restore function briefly but carry real risk and aren’t a long‑term fix. For long-term reliability or if repair costs approach replacement, prioritize file salvage and consider a professional board rework or a donor motherboard. (laptoprepair101.com)

Their diagnosis is sound, usually when machines do this it is the motherboard, however there are rare cases that a power supply could do this too. Do you hear the power on self test beeps during the 30 seconds it's on?

It is most likely the mother board in some way but it may not be broken. You should try to reset the bios settings before buying a new mother board. To do this either remove the cmos battery and turn the computer on and off and replace the battery or use the jumpers to flush the bios. (you will probably need your mother board book to do this)

good luck

Hi! I am very sorry to drudge up such an old thread but this is exactly the thing that is happening to my fiancee's Compaq v6000 (and seems to be a common issue for many). Now the computer is terrible and I don't really think its even worth fixing given how many people seem to have technical issues but the files on the computer are of extreme sentimental value and I am simply wondering if the data would be safe.

Also, in the case that it is not damaged how difficult would it be to go about getting the information off for a person who used to be decently versed in PC hardware. Would I be able to hook it up to a desktop? If anyone can offer any suggestions I would be so grateful (and so would she!) Thanks!

Hi,
I haven't bothered to read this old thread, you would have been better to open your own new thread and reference to this one.
If the laptop will not start you can not access it from another machine. You can remove the hard drive and connect it to another PC and take off the information you want.

Go to the HP site, look up your model details, download the service manual and see if you can do a restore.....

unfortunately Caperjack.... I don't get a post screen to even get bak to the bios and change the boot order.... Also is there a different type of motherboard that can b put into the compaq presario v6000 besides the 1 that it came with....
Thanks

usually a hard thing to do because of front case power button where they plug into the motherboard ,and the pack panel where the mouse and stuff plug in .but if your handy it can be done
